Viewfinder Panorama has an extensive collection of digital elevation models, panoramas and other mountain related information that is freely available for use, provided permission and credit is given.

The digital elevation models are based on the Shuttle Radar Topography Mission data, are in HGT format and are available for a number of mountainous areas, including the Himalayas, the Alps, New Zealand and Japan. In cases where the SRTM data provides a no-data cell, Viewfinder Panoramas (or, more accurately Jonathan de Ferranti) has filled in the cell with a value using other available sources. Plans are afoot to complete all the SRTM tiles in this manner - a multiyear project - but most of the world’s major mountain ranges are planned for completion this spring.

The panoramas available on the site are computer generated and some have a on the ground photograph to compare to (see the examples on the right).
